TAC Xenta OP Handbook 4 Dialogs with TAC Xenta 300 and 401

4.6 Edit access code

To change the code that gives the operator access to the medium or

high level items, the access level code for the level to be changed must

first be entered as described above. Then go to the Edit Access Code

screen:

A2: EDIT ACCESS CODE

EDIT CODE:

0000

Change code for

the active level (no.)

Use

to move the cursor between the digits and use

and

–

to change their value. When finished, press and leave the

menu with

. As the access code is changed only the standard

(low level) items will be shown. To show the medium or high level

menu items the new access code has to be entered as described in the

previous example.

After the download of an application from TAC Menta, the access

code will revert to the default value.

4.7 Overriding inputs/outputs

For access code high, it is possible to override the input and output

values in the Status displays of the OP.

For example, to override a digital output you must indicate “manual

override” in the field just in front of the displayed value:

A2: Fan status

SF_out _0

With the cursor in the position just to the left of the 0 value, use

–

twice to toggle up the manual override indicator (->).

Press

to confirm and to move the cursor to the value itself. It is

now possible to change the value, a value that will override the value

set by the controller.

The override indicator will remain visible (for all access levels) until

it is reset to normal, automatic mode.

Network Variables (please refer to the TAC Menta User’s manual)

can also be overridden in this way.
